### QuickForm3 calculations problem

Posted:

**Tue Jun 04, 2019 10:34 pm**Hello,

I am using QuickForms3 to create a calculator that will display heating costs. The link to the page (site still under development) is here: https://new.patioeg.com/index.php/calcu ... hroom-test

As you can see there are errors being shown. The required calculations are:

Total cost per hour=((Total BTU/1000000)*46)*(Cost of tank/15)

Total weekly cost=Total cost per hour*Hours per week

Total Yearly cost=Total weekly cost*Weeks per year

The equation I have put into multipl tab is:

5.0={5.7}+{5.8}+{5.9}+{5.10}+{5.11};

5.20=(({5.0}/1000000)*46)*({5.12}/15);

5.15={5.20}*{5.13};

5.16={5.15}{5.14}

The Total BTU {5.0} is being calculated, but then it is not pulling that total over into the next calculation {5.20}.

For the user input fields of Tank Cost{5.12}, Hours{5.13}, and Weeks{5.14} the "math" value is set to V.

Any help would be greatly appreciated. Thanks very much.
